Terron Armstead’s unofficial 40-yard dash time of 4.65 seconds shattered the previous NFL combine record for an offensive lineman (4.84), set by Allen Barbre in 2007. It was no fluke. On his second run, the former Arkansas Pine-Bluff standout clocked in with an unofficial time of 4.71. Not too shabby for a guy tipping the scales at 306 pounds.
